Yes, a significant new proposal could substantially improve how your retirement investments are protected. The U.S. Department of Labor announced on March 30, 2026, a major safe harbor proposal that creates clearer rules for how retirement plan fiduciaries can invest your money in alternative assets—everything from private equity and real estate to cryptocurrency and infrastructure investments. For the first time, the government is establishing a specific, process-based roadmap that fiduciaries can follow to demonstrate they’re acting in your best interest when selecting these complex, high-stakes investments. Instead of vague standards that leave retirees vulnerable to poor decision-making, this framework gives plan managers a clear path to prove they’ve done their homework. This proposal matters because alternative investments now make up a growing portion of retirement portfolios, yet the rules governing them have been murky.
Many plan sponsors have been hesitant to offer alternative investments to employees and retirees precisely because the legal standards were unclear, leaving them exposed to lawsuits even when their intentions were sound. For example, a pension fund that invests in private equity partnerships might struggle to justify that decision under current law, even if the investment performs well and meets strict criteria. The new framework removes that uncertainty by establishing six concrete factors that fiduciaries can use to make defensible decisions. The timing of this proposal is significant. It arrives after the Department of Labor’s broader Retirement Security Rule was vacated in March 2026, leaving a regulatory gap in how fiduciaries are protected. This new safe harbor is meant to fill that gap and provide more targeted guidance specifically around alternative investments.

Why the DOL Created a Safe Harbor for Alternative Investments
The Department of Labor created this safe harbor because retirement plan fiduciaries face an impossible balancing act. On one hand, fiduciaries have a legal obligation under the Employee Retirement Income Security Act (ERISA) to act in participants’ best interests and maximize returns. On the other hand, they’re also liable for breaching their duties if an investment underperforms or is deemed too risky. This creates a chilling effect where conservative plans stick only to stocks and bonds, even when alternative investments might offer better diversification and returns. Alternative investments have become essential tools for building resilient retirement portfolios.
Private equity can offer superior long-term returns; real estate provides inflation protection; infrastructure investments generate stable income streams. Yet without clear legal guidance, many plan sponsors have avoided these options entirely, leaving retirees with less diversified and potentially lower-returning portfolios. The safe harbor acknowledges this reality by saying: “If you follow these six steps, you’re protected—you won’t be sued successfully even if the investment later underperforms.” Consider a situation where a union pension plan wants to invest in a diversified real estate fund. Under the old ambiguous standards, the plan sponsor might face litigation from members claiming the decision was imprudent, even if the investment was carefully researched and performed reasonably well. Under the new safe harbor, if the sponsor followed the six-factor framework, they have a much stronger legal defense.
The Six-Factor Framework That Changes Everything
The Department of Labor’s safe harbor is built on six specific factors that fiduciaries must evaluate and document. First, they must assess fees and expenses—comparing the costs of the alternative investment against similar investments and ensuring fees are reasonable. Second, they must verify sufficient liquidity, meaning the investment must allow for redemptions or sales within a timeframe that matches participants’ retirement needs, not lock participants’ money away indefinitely. Third, the investment must have timely and accurate valuation, so plan sponsors can track whether the investment is actually worth what they claim and can report accurate values to participants. The fourth factor requires comparing performance against appropriate benchmarks—not just checking whether the investment made money, but whether it delivered returns comparable to similar investments in the same category.
For instance, a private equity fund should be measured against other private equity funds, not against the S&P 500. Fifth, fiduciaries must demonstrate they understand the investment’s complexity; they can’t simply delegate all decision-making without grasping what they’re investing in. Finally, the framework grants a “presumption of reasonableness” to fiduciaries who follow all six steps—a huge legal protection that essentially shields them from liability unless someone can prove they violated the framework. The limitation here is that this framework applies only to the selection and monitoring of alternative investments, not to everything else a plan does. A fiduciary who follows all six factors for selecting a private equity fund but then fails to monitor it, or invests in inappropriate amounts, could still face liability. Additionally, the burden of documentation is substantial; plans must maintain detailed records of how they evaluated each factor.
What Investments Does This Safe Harbor Actually Cover?
The safe harbor applies to a broad range of alternative investments: private equity, real estate (both commercial and residential), digital assets and cryptocurrency, commodities, infrastructure investments, and lifetime income strategies such as annuities. This is significant because it means the protection extends beyond just stocks and bonds. A 401(k) plan that offers a self-directed brokerage option allowing participants to buy cryptocurrency, or a pension fund investing in renewable energy infrastructure, would fall under this framework. However, the coverage isn’t universal. The proposal specifically addresses alternative investments—assets that aren’t typical publicly traded stocks or bonds.
That means a plan offering a standard S&P 500 index fund or a bond mutual fund wouldn’t need to follow this framework; those investments are already well-understood and have long-established fiduciary standards. The safe harbor is designed for the newer, more complex asset classes where legal uncertainty has been a real barrier to investment. A concrete example: imagine a state pension system that wants to invest $500 million in a diversified infrastructure fund covering toll roads, water systems, and power plants. Under the old rules, the pension board might have feared litigation from retirees claiming the investment was too risky or poorly selected. Under the new framework, if the board documents that it evaluated the six factors—checked fees against comparable infrastructure funds, confirmed liquidity through regular redemptions, verified independent valuation, compared performance to infrastructure benchmarks, understood the complexity of the portfolio, and created a monitoring plan—the board gains substantial legal protection.
How This Proposal Differs From Previous Regulatory Attempts
The Department of Labor previously proposed the broader Retirement Security Rule in 2024, which would have expanded fiduciary protections across many areas of retirement plan management. That rule was vacated in March 2026, leaving a regulatory void. The new safe harbor is much more narrowly tailored—it focuses specifically on alternative investments rather than trying to overhaul the entire fiduciary framework. This focused approach has both advantages and drawbacks. The advantage is that a narrower proposal is more likely to survive legal challenges and implement faster. Alternative investments are a discrete, identifiable problem with clear solutions, whereas the broader Retirement Security Rule tried to tackle multiple issues at once. The disadvantage is that this safe harbor leaves many other fiduciary questions unresolved.
Plan sponsors still lack clear guidance on areas like fee selection for traditional investments, participant education, or conflict-of-interest handling. So while the alternative investment space gets new clarity, other areas remain in legal limbo. The difference is also practical. The old Retirement Security Rule attempted to protect small plan sponsors through expanded guidance and prohibited transaction exemptions. The new safe harbor doesn’t include those broader protections; it’s designed mainly for alternative investments. This means that small 401(k) plans seeking guidance on how to select a stable value fund or offer a self-directed brokerage option still don’t have a clear safe harbor. The proposal essentially says: “We’re solving the alternative investment problem, but other issues will have to wait.”.
How SECURE 2.0 and Recent Changes Layer Onto This Framework
While the DOL was creating this safe harbor, Congress passed SECURE 2.0, which took effect at various points during 2025 and 2026. One critical change allows plan participants aged 60-63 to make larger catch-up contributions to retirement accounts—currently $7,500 above normal limits, an amount that will adjust yearly. Additionally, starting January 1, 2026, catch-up contributions for higher-income earners (those making over $150,000 in FICA compensation) must be made as Roth contributions, meaning they’re taxed now but grow tax-free. These changes affect how the alternative investment safe harbor matters. More money flowing into retirement accounts, especially into catch-up contributions, creates pressure to find higher-returning investments. The DOL’s safe harbor for alternative investments addresses this directly—it makes it legally safer for plans to offer private equity, real estate, and other alternatives that might deliver better returns for the additional money participants are contributing.
However, there’s a warning embedded here: SECURE 2.0’s Roth catch-up requirement means older, higher-income workers must give up the traditional tax deduction when making these additional contributions. That’s a real tradeoff—higher lifetime returns potential, but lower immediate tax savings. The Social Security Fairness Act, enacted January 5, 2025, has also changed the retirement security landscape. Over 3.1 million payments totaling $17 billion were distributed by July 7, 2025, as the government processed claims from public sector workers affected by the old Windfall Elimination Provision and Government Pension Offset. These payments represent real money returning to retirees’ pockets—an average increase in monthly benefits for affected individuals. This doesn’t directly interact with the alternative investment proposal, but it does mean that some retirees are now in better financial positions, potentially able to take more investment risk and benefit from higher-returning alternative investments.
What Plan Sponsors and Retirees Should Do Now
For plan sponsors—the companies and unions running retirement plans—this proposal creates both opportunity and obligation. The opportunity is that you can now confidently offer more sophisticated investment options. The obligation is that offering these options means you must follow the six-factor framework meticulously, documenting every step. If you’re considering adding a private equity option, a real estate fund, or an infrastructure investment to your plan, now is the time to prepare. You’ll need to assemble investment expertise, establish monitoring procedures, and create a documentation system. For retirees and plan participants, this proposal is good news, but it requires vigilance.
You should understand what alternative investments your plan is offering and why. If your plan suddenly starts offering cryptocurrency, infrastructure funds, or private equity, ask the investment committee how they evaluated the six factors. A plan that can clearly explain its reasoning is one that has done the work required by the safe harbor. A plan that cannot explain why an alternative investment was selected is one that might not have followed proper procedures—a red flag. One practical consideration: many plan participants don’t have the expertise to evaluate alternative investments themselves. This is where the safe harbor’s requirement that fiduciaries “understand the complexity” becomes important. It’s not your job as a participant to become an expert in private equity valuations; it’s the plan sponsor’s job to ensure that whoever is making the decision actually understands what they’re buying.
What Comes Next in Retirement Security Legislation
The landscape for retirement security regulation is in flux. The Department of Labor hasn’t abandoned its broader mission; instead, it’s taking a more targeted approach with proposals like this safe harbor. The Insured Retirement Institute released a 2026 Retirement Security Blueprint containing 33 different proposals to strengthen retirement systems, including the Auto Re-Enroll Act of 2025 (which would automatically re-enroll workers who drop out of their plans after job changes) and the Retirement Fairness for Charities and Educational Institutions Act of 2025 (which would allow these organizations to create multi-employer plans).
Additionally, the Senior Citizens’ Freedom to Work Act has been proposed, which would repeal the retirement earnings test that currently reduces Social Security benefits for working retirees under full retirement age. This matters because it would allow older workers to keep working without facing benefit reductions, potentially allowing them to defer claiming Social Security and receive higher lifetime benefits. Together, these proposals suggest a regulatory environment moving toward greater flexibility and protection for retirement savers. The safe harbor for alternative investments is one piece of a larger puzzle aimed at making retirement security more robust and offering more options for building resilient retirement income.
Conclusion
The Department of Labor’s safe harbor proposal represents a genuine shift in how retirement investment safety is regulated. Instead of vague standards that leave fiduciaries paralyzed and retirees underserved, the six-factor framework provides clarity and legal protection. This means plans can confidently offer better-diversified portfolios including private equity, real estate, infrastructure, and other alternatives—investments that can deliver higher returns and better inflation protection. For retirees, this translates into potentially stronger retirement security through access to more sophisticated, better-managed investment options. The key is that this framework works only if plans actually follow it.
Document your decisions. Understand the investments you’re offering. Monitor performance and liquidity. Fiduciaries who treat the six factors as a checkbox exercise rather than a genuine framework for sound decision-making may still face legal challenges. But plans that take the framework seriously—that genuinely evaluate fees, liquidity, valuation, benchmarks, complexity, and establish monitoring protocols—will find that the safe harbor actually protects them and, more importantly, protects the retirees depending on their decisions. In the coming months and years as the proposal moves toward finalization, pay attention to how your plan adapts.
